Energy efficient heating.



The cost of running your floor as a energy efficient heater.


How much will it cost to heat with radiant electric in-floor heating?     

As simple as this question is, the answer is not but the good news is: it is easy to find out.

 

It depends when (month of the year). It depends where you are by way of the rate per kWh (1000 Watts per hour). It depends on the climate zone, how energy efficient is your house and what temperatures you perceive as comfortable.

Rates vary. From as much as 16 in Hawaii, 15 in New York, almost 13 in Vermont and New Hampshire or California to as little as 6 in Kentucky.

 

 

 

Let's say you are in NJ where the rate is 11 cents per 1 kWh. 1 kWh is 1000Watts run CONSTANTLY for an hour. Our 111 sq.ft. mat (like MG100/10.0/240V) happends to be 1000 Watts or...yes 1 kW. If constantly run for an hour, in NJ, in 2006 it will cost 11 cents. On average, wintertime, floor heating connected to the programmable thermostat will run for 10 hours or so. This said, it will cost $1.10 every day in the winter.

Expensive? Think again. Unlike oil or gas, electric is often regulated and your local utility will have a hard time to do what your local gas station or heating oil supplier does day-in and day-out: change the numbers on the boards high in the sky, next to the highway. But wait, wait, there is more. Is there anythig good in the future of oil? Who knows. So far - not so good. How about electric? Well...

 

Is this how your future roof is going to look like?

 

 

Each of the PV panels on this pretty picture perfect roof is making near 100 Watts of CLEAN power on the sunny day! That's 11 sq.ft. of our floor heating. No moving parts, no pumps, no plumbers. Just silicone, wires and electronic controlls. And best of all:

IT IS CLEAN, GREEN RENEWABLE ENERGY, the way energy should be.

More on Energy Efficiency of your home:

 

 

Heating and Cooling

 

 During most months, heating and cooling accounts for the bulk of your energy bill. So taking steps to make your heating and cooling system more efficient can pay big dividends in the long run.

 

Here are some things that you can do to reduce your monthly heating and cooling costs:

 

         In the winter, set your thermostat at 68 degrees.

 

         In the summer, set your thermostat at 78 degrees.

 

         Change or clean the filter(s) on your forced-air heating and cooling system monthly. An obstructed filter raises heating and cooling costs significantly.

 

         Close or seal vents to rarely used rooms.

 

         Keep the damper of your fireplace tightly closed when it's not in use.

 

         Check your home's ductwork to ensure that it's properly insulated and that there are no air leaks or gaps.

 

 

Insulation.

According to 'Today's Homeowner', heating and air conditioning account for 50 to 70 percent of the energy most American homes use. Home insulation is one of the best ways to increase energy-efficiency and reduce the amount of money you spend each month on heating and cooling. Yet most homes aren't as well insulated as they should be.

Check these areas of your home to see if they're properly insulated.  The energy experts at your local electric cooperative can tell you exactly how much insulation each of these areas requires.

 

         Your attic, including the attic door or hatch.

 

         The area beneath floors above unheated space (basements, crawl spaces).

 

         Around the walls in a heated basement or unventilated crawl spaces.

 

         Along the edges of slabs-on-grade.

         Around ductwork that passes through unheated areas.

 

In areas where you can reach the framing structure, it's easy to add insulation yourself. For hard-to-reach areas, check with a qualified, licensed insulation contractor to determine the price and extent of the work your home needs.

 

Lighting


Improving your lighting efficiency is one of the easiest ways to decrease your energy bills.

According to the U.S. Department of Energy, if you replace 25 percent of your incandescent lights in high-use areas with fluorescents, you can cut your lighting energy bill by about 50 percent.

Fluorescent lamps are much more efficient than incandescent bulbs and last six to 10 times longer. Although fluorescent and compact fluorescent lamps are more expensive than incandescent bulbs, they pay for themselves by saving energy over their lifetime. New LED lights are super efficient but still fairly expensive.

 

Doors and Windows


The condition of your home's windows and doors can have a lot to do with your monthly energy bill. According to the U.S. Department of Energy, the heat lost through and around windows can account for 10 to 25 percent of your winter heating bill.
Here are some things you can do to reduce the heating and cooling energy lost around your home's doors and windows:


 

         Replace old, single-pane windows with new, energy-efficient double-pane windows.

 

         Install storm doors and windows. If you cannot afford storm windows, use plastic sheeting to act as temporary storm windows.

 

         Hang heavy, insulated curtains in front of windows.

 

         Seal cracks around window frames and door jams with caulk.

 

         Install weather-stripping around windows and doors.

 

         Install door sweeps along the bottom edge of all exterior doors.

 

Appliances

 

Appliances such as refrigerators, water heaters, and clothes washers and dryers can be big energy users.

Here are some suggestions from the Rocky Mountain Institute to help you reduce the amount of energy used by your appliances:

 

Refrigerator:

 

         For maximum food safety and energy efficiency, set the thermostat in your refrigerator at 35 to 40 degrees F. Set the freezer at 0 to 5 degrees F.

 

         Clean and/or vacuum the condenser coils once per year.

 

Water Heater:

 

         Insulate your water heater with a water heater blanket.

 

         Set the thermostat on your water heater at 115 degrees F.

 

Clothes Washer and Dryer:

 

         Wash full loads whenever possible or use lower water level settings for small loads.

 

         Don't overfill your clothes dryer. Warm air must circulate around the clothes to dry them.

 

         Dry two or more loads of clothes back-to-back to make use of leftover heat in the dryer.

 

         Clean the dryer's lint trap often. A full lint trap keeps the warm air from circulating and overworks the dryer.

 

Inside Tips


Off when you're out: If you use a window air-conditioner, turn it off when you leave a room for several hours. You will use less energy cooling the room down later than if you had left the unit running.


Use Fans: Turn your air-conditioner off on cooler days. Open the windows early in the morning when it is still cool and/or turn on fans. On days when you just need a bit of a breeze or on pleasant nights, a ceiling fan alone can do the job. Small portable fans set at floor level, larger window fans to pull cool air inside or draft hot air out, and whole-house or attic fans are other cooling options.


Vent Blocked: Keep air vent clear of obstructions like books or furniture.


Crawl Space Vents: Vents should be opened during the spring and summer because many areas have problems with moisture under the home. Closing the vents during spring and summer can trap the moisture and cause a problem.

Bathroom Ventilation Vents: It is wise to run ventilation fans in your bathrooms during and 20 minutes after a shower or bath to remove excess moisture in your home. However, running fans too long can siphon cool, conditioned air you want in your house to the outside.


Shade Your Windows: Keep out the sun with shades and/or curtains and keep lights low or off.


Time Your Chores: Wait until cooler hours to do chores that add humidity to the air, such as washing and drying clothes, washing dishes, and cooking, and use ventilation fans in bathrooms and kitchens to help vent that extra moisture.


Painting Soon? If you're doing some interior painting this spring or summer, choose light colors. Pale shades reflect sunlight, requiring less lighting.


Read the Manual: It's always a good idea to hang on to appliance manuals so you can refer to them for care information and possible energy-saving tips.
